SPECIFICATION forming part of Letters Patent No. 513,657, dated January30, 1894.

Application tiled November 15, 1893. Serial No. 491,013. (No model.)

Io ling device for car coupler links.

The object of my invention is to provide a link controlling device to beused in coupling cars together where the cars have draw-heads of thesame or different heights which will render it unnecessary for a personto go between the cars during the operation.

A further object of my invention is to provide a simple constructionwhich may be cheaply manufactured and be readily atzo tached to anydraw-head.

For a full and complete understanding of my invention, reference is tobe had to the accompanying drawings, in which- Figure 1 is a centrallongitudinal sectional view of two draw-heads illustrating my invention.Fig. 2 is a plan view of a draw head having a link and the controllingdevice attached thereto. Fig. 3 is a view in side elevation of the linkcontrolling device detached 5o from the draw head.

In the drawings, A refers to the draw heads.

B represents the mouth of the draw head with iiaring sides of usualform. The lower inside surface b of the mouth is of 'curved Centrallylocated lengthwise in this lower surface is a groove h which risesgradually as it slopes to the rear. A corresponding groove b2 is cut inthe upper surface of the mouth of the draw-head over 4o the lower groovefor a purpose which will hereinafter appear. These grooves haveperpendicular walls b3 at their outer ends as shown.

C is a hole in the upper front part of the mouth of theV draw head,preferably of elongated form, see Fig. 2, for the insertion of a 5o lingpin when it is in the rear end of the elongated hole C to prevent thepin from jumping out of the hole, see Fig. 1, but which does notinterfere with the ready withdrawal of the pin when it is moved into aforward position, as will readily appear.

in the side walls of the casing is mounted a double crank F on its armsf and having end arms f extending to the sides of thecar to permit thecrank to thereby be operated without the necessity of a person goingbetween the cars. Near the middle of said crank and equi-distant apartare mounted two rods Gr to turn upon the crank as the latter is moved.These arms pass through apertures g in the upper part of the draw-headin rear of the coupling pin, and have enlarged ends g to bear upon thesides of the coupling link when it is inserted in the mouth of the drawhead.

The operation of the device is, as follows, see Fig. l: Then it isdesired to couple two cars together which are coming together, a personstanding at the side of one of the cars, Operates the double crank bymeans of the handle on the end of arm f', and by means of the rods Gwhich bear upon the side of the link and the curved shape of the lowersurface of the mouth of the draw-head upon which the link rests, raisesor lowers the outward end of the coupling link so that it will pass intothe mouth of the draw head on the opposite car, push back the pin inthat draw head, owing to the cut away grooves therein, pass beyond thelink thus permitting it to drop back in place, in a well known manner,and in this manner the cars are readily coupled without eXposing thelife of the operator, as in the old practice where it is necessary for aperson to go between the cars to do the coupling.

Having thus described my invention, what 1 desire to secure by LettersPatent is- 1. 1n a car coupler, the combination witha draw-head of amouth with cut away portion on its lower surface of curved contour, oflongitudinal grooves centrally located in the upper and lower surfacesof the mouth, a coupling pin adapted to be pushed backward in saidgrooves, a casing on top of the drawhead, a double crank mounted in theside walls of the casing and having arms extending outwardly to thesides of the car, rods ICO centrally and revolubly attached thereto andextending through apertures in rear of the coupling pin into the mouthof the draw head, enlarged ends on the lower extremities of the rods tobear upon the sides of a coupling link to raise orlower the same,substantially as described and set forth.

2. The combination in a oar coupler of a draw-head with a cut awayportion on its lower surface of curved contour, of longitudinal andcentrally located grooves in the upper and lower surfaces of the mouth,a coupling pin adapted to be pushed backward in said grooves, a casingon top of the draw head, a crank mounted in the sidewalls of the casingand having arms extending outwardly to the sides of the car, rodscentrally attached to said crank and extending through apertures in theupper part of the drawhead, enlarged lower ends on the rods to bear uponthe ycoupling link to raise and lower the same,

as and for the purposes set forth.

3. An automatic car coupler comprising a draw head with a cut awayportion in the lower surface of the mouth, grooves in the upper andlower surfaces of the mouth centrally and longitudinally located topermit a coupling pin to be moved backward and forward from an uprightposition, an elongated hole in the upper part of the mouth for theinsertion of a coupling pin, a projection above the rear portion of thehole,` a casing on top of the draw-head, a double crank mounted in thesides of the casing and having outwardly extending arms, rods attachedcentrally to said crank and extending through apertures in the draw headin rear of the coupling pin, to contact with a coupling link to raise orlower the same, substantially as described and set forth.

In testimony whereof I affix my signature in presence of two witnesses.
